Notes to Consolidated Financial Statements

Note 1 – Accounting Policies

Basis of Presentation

The consolidated financial statements have been prepared by Deltic Timber Corporation (the “Company” or “Deltic”). Certain information and accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations of the Securities and Exchange Commission. Although management of the Company believes the disclosures contained herein are adequate to make the information presented not misleading, these consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2016. Preparation of consolidated financial statements requires management to make estimates and assumptions. These estimates and assumptions affect reported amounts of assets and liabilities, disclosure of contingent assets, and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Management believes the accompanying consolidated financial statements contain all adjustments, consisting of only normal recurring accruals and adjustments, which in the opinion of management are necessary to present fairly its financial position as of September 30, 2017, and the results of its operations and cash flows for the three months and nine months ended September 30, 2017 and 2016. These consolidated financial statements are not necessarily indicative of results to be expected for the full year. The Company has evaluated subsequent events through the date the financial statements were issued.

Recently Issued Authoritative Accounting Pronouncements and Guidance

Effective January 1, 2017, the Company adopted Accounting Standard's Update ("ASU") 2016-09, “Improvements to Employee Share-Based Payment Accounting”. This standards update simplified several aspects of the accounting for share-based payments award transactions, including accounting for income taxes, classification of excess tax benefits on the statement of cash flows, forfeitures, minimum statutory tax withholding requirements, and the classification on the statement of cash flows of employee taxes paid when an employer withholds shares for tax-withholding purposes. As a result of the adoption, Deltic recognized approximately $500,000 of tax shortfalls from share-based compensation as a discrete item of income tax expense during the first quarter of 2017. Historically, these amounts were recorded as activity in additional paid-in capital. Deltic elected to apply the standards update pertaining to cash flows prospectively, therefore prior-year statements have not been adjusted. Deltic elected to account for forfeitures as they occur rather than using a requisite estimated forfeiture rate for future forfeitures. The additional changes related to the standard's update and the election to change accounting methods for forfeitures did not have a material impact on the Company's financial statements.

Effective January 1, 2017, the Company adopted ASU 2015-17, "Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes". This standards update requires that all deferred tax assets and liabilities be offset and presented as a single, non-current, amount. Historically, deferred tax items were presented on the Balance Sheet as current and non-current. The Company applied this standard's update prospectively, combining current deferred tax assets of $1,895,000 with non-current deferred tax liabilities, for a net long-term tax asset balance of $151,000 at January 1, 2017.

In March of 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-07, "Improvements to the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which requires the service cost components be reported separately from other components of net

periodic pension costs and be reported on the same line item as other compensation costs. This update is effective for the Company on January 1, 2018 and is not expected to have a material impact on its financial statements.

In May of 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue it expects to be entitled to for the transfer of promised goods or services to customers. This ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. The Company continues to evaluate the standard and has not yet selected a transition method but believes the standard is expected to have little impact on its consolidated financial statements other than updated disclosures.

In February 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-02, “Leases”, which supersedes Topic 840 and among other things, requires lessees to recognize most leases on-balance sheet. The new standard will be effective for the Company on January 1, 2019, and is not expected to have a material impact on its financial statements.

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments”. The ASU changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life. This update will be effective for the Company on January 1, 2020, and is not expected to have a material impact on its financial statements.

	$	356,034		360,183

Deltic acquired 341 acres of timberland for $353,000 during the three and nine months ended September 30, 2017. During the three months ended September 30, 2016, Deltic acquired 220 acres of timberland for $514,000, and for the nine months ended September 30, 2016, Deltic acquired 623 acres of timberland for $1,207,000. Deltic invests in and holds strategic fee timber as a productive asset, and any expenditure to acquire such timber and timberlands is an investing activity on the Company’s Consolidated Statements of Cash Flows.

The Company actively upgrades its timberland portfolio by selling non-strategic timberlands and using the sales proceeds to purchase pine timberlands that are strategic to its operations. The Company identifies tracts of pine timberland that cannot be strategically managed due to size or location, and also tracts of hardwood bottomland that cannot be converted into pine-growing acreage, to be sold. As of September 30, 2017, approximately 1,500 acres of these lands were available for sale.

Note 8 – Income Taxes

The Company’s effective income tax rate for the three months and nine months ended September 30, 2017, was 39 and 43 percent, respectively. This compares to an effective income tax rate for the three and nine months ended September 30, 2016, of 38 and 33 percent, respectively. The prior-year effective rate was reduced by the lower capital gains tax rates applied on the sale of timber held 15 years or longer which expired December 31, 2016. Conversely, the effective income tax rate exceeded statutory income tax rates during the first nine months of 2017 due to discrete items related to the changes in the method of recognizing income tax benefits and shortfalls on the vesting of share-based compensation by the adoption of ASU 2016-09 in the first quarter. At September 30, 2017, there were no unrecognized tax benefits recorded on the balance sheet. The Company is no longer subject to U.S. federal and state examination by tax authorities for years before 2013.

Note 13 – Fair Value of Financial Instruments

Fair Value Measurement Accounting establishes a fair value hierarchy based on the quality of inputs used to measure fair value, with Level 1 being the highest quality and Level 3 being the lowest quality. Level 1 inputs are quoted prices in active markets on identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included in Level 1. Level 3 inputs are unobservable inputs which reflect assumptions about pricing by market participants.

The following is a description of the valuation methodologies used for assets and liabilities measured at fair value.

Nonqualified employee savings plan – Consists of mutual funds, which are valued at the net asset value of shares held by the plan at the balance sheet date, at quoted market prices.

The fair value measurements for the Company’s financial liabilities accounted for at fair value on a recurring basis at September 30, 2017, are presented in the following table

	Fair Value Measurements at Reporting Date using

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Executive Overview

The Company reported net income of $2.5 million for the third quarter of 2017, compared to $1.5 million for the same period of 2016. The financial results for the quarter benefited from higher operating income from the Woodlands and Real Estate segments, combined with reduced Corporate expense and was partially offset by reduced operating income from the Manufacturing segment. The Woodlands segment reported $5.4 million in operating income for the third quarter of 2017, an increase of $1.3 million when compared to 2016 primarily due to an increase in volume of timber sold. The Manufacturing segment reported $3.7 million in operating income, a decrease of $2 million from $5.7 million reported a year ago. The change was due primarily to lower MDF production resulting from scheduled downtime at the medium density fiberboard ("MDF") plant, combined with increased per-unit cost of lumber produced, as the integration process of the regular and small log lines at the Ola mill continued into the third quarter of 2017. The Real Estate segment reported operating income of $1 million in the third quarter of 2017, a $1.2 million increase from 2016 due to the an increase in the number of residential lots sold. Corporate segment operating expense was $1.3 million lower in the current-year quarter than in the same period a year ago, primarily due to decreased general and administrative expenses.

Deltic is a natural resources company operating in a commodity-based business environment that is engaged in the growing and harvesting of timber and the manufacture and marketing of lumber and MDF, with a major diversification in real estate development. The Company’s operating and financial results are affected by a number of factors, which include, but are not limited to, housing starts, general economic conditions, United States employment levels, interest rates, credit availability and associated costs, imports of lumber and MDF, foreign exchange rates, new and existing home inventories, residential and commercial real estate foreclosures, residential and commercial repair and remodeling, commercial construction, industry capacity and production levels, availability of skilled manufacturing labor, the availability of raw materials, natural gas pricing, and weather conditions. Sawmill curtailments related to wildfires in British Columbia increased the market demand for southern yellow pine lumber. Demand for new housing continues to be stronger than the supply as year-to-date single family housing starts are 6.9 percent higher than a year ago. The Company continues to develop residential lots in its Chenal Valley and Wildwood developments to provide a mix of price points available in residential lots for sale.

The Woodlands segment is the Company’s core operating segment, and its pine timberlands supply the majority of raw material logs to Company sawmills with the remainder sold to third parties. In the third quarter of 2017, the pine sawtimber harvest was 196,635 tons, an increase of 7,992 tons when compared to the 2016third quarter harvest of 188,643 tons. The average sales price for the pine sawtimber harvested was $28 per ton in the third quarter of both 2017 and 2016. The chip-n-saw harvest was 19,482 tons compared to 4,460 tons harvested in the third quarter of 2016 while the per-ton average sales price was $1 higher at $17 per-ton. Completion of the small-log line at the Ola Mill in late 2016 has allowed the company to better utilize the smaller chip-n-saw sized log for lumber production. The pine pulpwood harvest in the current-year quarter was 153,665 tons, an increase of 29,003 tons from the harvest volume in the third quarter of 2016, and the average sales price for pine pulpwood was $7 per ton in the third quarter of both 2017 and 2016.

The Woodlands segment’s financial results include other ancillary benefits from land ownership, such as revenues from hunting leases, mineral lease rentals, and mineral royalties. Hunting lease revenue was $.8 million for the third quarter of both 2017 and 2016. Oil and gas royalty income, primarily from gas wells in the Fayetteville Shale Play, was $.6 million in the third quarter of 2017, a $.2 million increase from the third quarter of 2016, due to an increase in natural gas prices, partially offset by the impact of declining production volume from the aging of existing gas wells and lack of new drilling activity. Deltic is currently receiving royalty income from 508 wells in the Fayetteville Shale Play; however, the Company’s income from mineral ownership in future periods is contingent on natural gas and crude oil prices, successful completion of producing wells drilled on Company lands, and leasing additional acreage.

The Manufacturing segment produces both dimension lumber and MDF. The Company’s sawmill operations sold 80.5 million board feet of lumber in the third quarter of 2017, an increase of 10.8 million board feet from the prior-year third quarter. The average lumber sales price in the third quarter of 2017 was $361

20

per thousand board feet, a $15 per thousand board feet, or four percent, decrease when compared to the same period in 2016. MDF sales volume was 23.9 million square feet for the third quarter of 2017, a decrease of 2.2 million square feet when compared to the same period in 2016, due to the scheduled plant downtime in August 2017. The average sales price for MDF in the current-year third quarter was $560 per thousand square feet, a slight decrease from $561 per thousand square feet received in the 2016 third quarter. Since the completion of the replacement of the press chains and a press belt, the MDF plant is operating at a much greater rate of efficiency and higher uptime percentage.

The Real Estate segment reported sales of 72 residential lots at an average sales price of $63,000 per lot during the third quarter of 2017, compared to 25 lots sold at an average sales price of $70,000 per lot in the third quarter of 2016. The decrease in sales price is due to the mix of lots sold. The timing of residential lot sales is determined by the available lot inventory. Lots in three neighborhoods in Chenal Valley and additional Wildwood lots are currently being developed to be offered for sale later in the year. There were no sales of commercial acreage during the third quarter of 2017 or 2016. The commercial real estate acreage within Chenal Valley continues to receive interest from potential buyers and in October 2017 Deltic sold the Company-owned, 35,000-square-foot retail center which is located at the key intersection of Rahling Road and Chenal Parkway for approximately $4 million. Due to the unpredictable nature of commercial real estate sales activity, the Company cannot predict the timing of closing of any other commercial real estate transaction.

Consolidated

Consolidated net income for the third quarter of 2017 was $2.5 million, an increase of $1 million from the third quarter of 2016. The increase was primarily due to improved financial results for the Woodlands and Real Estate segments combined with the benefit of lower Corporate general and administrative expense, partially offset by lower results from the Manufacturing segment.

Consolidated net sales increased $8.1 million, or 15 percent, from the third quarter of 2016, primarily due to the following:

• Woodlands segment sales increased $2.3 million, due to increased harvest of pine sawtimber, pine chip-n-saw and pine pulpwood

• Manufacturing segment sales increased $1.8 million, due to a four percent increase in the volume of lumber sold

22

• Real Estate segment net sales increased $2.9 million, due to an increase in residential lots sold

Consolidated cost of sales increased $6.3 million compared to the third quarter of 2016, primarily due to the following:

• Manufacturing segment cost of sales increased $3.4 million due to higher direct operating costs associated with an increase in operating days and lumber production at the sawmills, partially offset by lower direct manufacturing costs at the MDF plant due to lower MDF production caused by scheduled downtime to complete capital projects

• Real Estate segment cost of sales increased $1.6 million due to an increase in the number of residential lots sold

Consolidated operating income increased $1.7 million due to the increases in sales, offset by increases in cost of sales as explained as above and higher depreciation expense at the sawmills.

The main cost drivers affecting the Company’s cost of sales and impacting each segment’s operating income and thus consolidated operating income are as follows: Woodlands – direct operating expenses (operating salaries and benefits, cull timber removal, line and road maintenance expenses, etc.), oil and gas royalty expenses, cost of hauling stumpage to other mills, and cost of timberland sold; Manufacturing – raw materials cost, direct manufacturing expenses (operating salaries and benefits, utilities, insurance, property and business interruption insurance deductibles, repairs and maintenance, etc.), and freight expense; and Real Estate – cost of residential lots, commercial acreage, and speculative homes sold and the cost of sales of Chenal Country Club.

Operating income	$	5.4	4.1	1.3

In the Woodlands segment, net sales for the third quarter of 2017 increased 26 percent from the same period of 2016, primarily due to the following:

•Pine sawtimber volume sold increased four percent, with no change in average per ton

sales price

•Pine chip-n-saw volume sold increased 337 percent, due to increased small-log utilization at

the Ola mill, with no change in average per ton sales price

•Pine pulpwood volume sold increased 23 percent, with no change in average per ton

sales price

•Hardwood sawtimber revenues increased due to an increase in volume sold, primarily

through timber deed sales

24

Cost of sales for the Woodlands segment increased during the third quarter of 2017 when compared to the same period of 2016 mainly due to increased stumpage hauling costs related to higher harvest volumes during the quarter.

The Woodlands segment's operating income increased $1.3 million from the third quarter of 2016, due to the same factors affecting net sales and cost of sales, combined with an increase in the cost of fee timber harvested due to volumes sold and general and administrative expenses allocated to the segment.

Selected statistical data for the Woodlands segment is shown in the following table.

¹Residual by-products are reported net of intercompany eliminations of $1.8 million in 2017 and $1.5 million in 2016.

Net sales for the Manufacturing segment increased $1.8 million from the prior-year period, primarily due to the following:

•Lumber revenues increased 11 percent due to 16 percent higher sales volume, partially

offset by a 4 percent decrease in the average sales price per MBF sold

•MDF revenues decreased eight percent due to sales volumes being eight percent lower than    

the prior-year quarter and of $1 per MSF lower average sales price

26

Cost of Sales for the Manufacturing segment increased $3.4 million during the third quarter of 2017 when compared to the same quarter a year ago. Intersegment elimination of residual sales by sawmill operations to the MDF operation are not reflected for the reported cost of sales for sawmill and MDF.

• Sawmill direct manufacturing expense increased 26 percent due to increased operating days and raw material costs at the sawmills, as lumber production increased 7 percent to meet market demand

•Direct manufacturing expense at the MDF plant was lower due to fewer operating

days during planned downtime to replace the worn press chains and a press belt

Operating income for the Manufacturing segment was $2 million less than in the same period a year ago, due to the same items affecting net sales and cost of sales, combined with a $.4 million increase in depreciation and $.3 million increase in general and administrative expense allocated to the segment.

Net sales for the Real Estate segment during the third quarter of 2017 increased $2.9 million when compared to the third quarter of 2016, due to the following:

• Sold 72 residential lots in third quarter of 2017 compared to 25 lots in the prior-year third quarter

•Average sales price decreased to $63,000 per lot in 2017 versus $70,000 per lot in the same quarter

of 2016 due to the mix of lots sold

Cost of sales for the Real Estate segment increased $1.6 million compared to the third quarter of 2016, due to the increased number of residential lots sold in 2017 versus 2016.

Operating income for the Real Estate segment increased $1.2 million compared to third quarter of 2016 due to the same factors affecting net sales and cost of sales.

Corporate

The Corporate operating expense in the third quarter of 2017 was 21 percent lower than in the third quarter of 2016 due to a decrease in general and administrative expenses, primarily salaries and benefits and incentive expense.

Eliminations

Intersegment sales of timber from Deltic’s Woodlands to the Manufacturing segment decreased $1.1 million to $4.2 million during the third quarter of 2017. Logs supplied by the Woodlands segment to Company sawmills are transferred at prices that approximate market.

Interest Expense

Interest expense was $2.2 million for the third quarter of both 2017 and 2016.

Income Taxes

The effective income tax rate was 39 percent for the three months ended September 30, 2017, and 38 percent for the three months ended September 30, 2016.

Consolidated

Consolidated net income for the first nine months of 2017 was $6.3 million, an increase of $.2 million when compared to the first nine months of 2016. The increase in operating income from the Woodlands and Real Estate segments and lower Corporate general and administrative expenses of $4.6 million was largely offset by decreased operating income from the Manufacturing segment.

Consolidated net sales increased $9.3 million from the first nine months of 2016, primarily due to the following:

•Woodlands segment sales increased 12 percent primarily due to increased revenues from

pine sawtimber, pine chip-n-saw, hardwood sawtimber, and oil and gas royalties

• Manufacturing segment sales increased $3.2 million, due to an $11 increase in the average sales price per MBF sold, a four percent increase in lumber sales volume, partially offset by lower MDF sales

• Real Estate segment net sales increased $1.7 million, due to an increase in the number of residential lots sold

30

Consolidated cost of sales increased $6.9 million compared to the first nine months of 2016, primarily due to the following:

• Woodlands segment cost of sales increased $1.3 million mainly due to increased hauling cost due to higher harvest volumes

• Manufacturing segment cost of sales increased $6.6 million primarily due to increased raw material and direct operating costs related to increased operating days and lumber production at the sawmills. These increases were partially offset by reduced direct manufacturing and raw material costs at the MDF plant due to fewer operating days and less MDF production as the plant completed capital projects to replace the worn press chains and a press belt during the current year

Consolidated operating income increased $.5 million due to the increases in sales and cost of sales as explained as above, combined with higher depreciation expense, partially offset by lower Corporate general and administrative expenses.

The main cost drivers affecting the Company’s cost of sales and impacting each segment’s operating income and thus consolidated operating income are as follows: Woodlands – direct operating expenses (operating salaries and benefits, cull timber removal, line and road maintenance expenses, etc.), oil and gas royalty expenses, cost of hauling stumpage to other mills, and cost of timberland sold; Manufacturing – raw materials cost, direct manufacturing expenses (operating salaries and benefits, utilities, insurance, property and business interruption insurance deductibles, repairs and maintenance, etc.), and freight expense; and Real Estate – cost of residential lots, commercial acreage, and speculative homes sold and the cost of sales of Chenal Country Club.

In the Woodlands segment, net sales for the first nine months of 2017 increased $3.4 million from the same period of 2016, primarily due to the following:

• Pine sawtimber revenues increased due to a three percent increase in harvest volume with no change in average per-ton sales price

•Pine chip-n-saw revenue increased due to the harvest volume increase of 137 percent, with

no change in average sales price

•Hardwood sawtimber revenue increased $.6 million due to increased harvest volume

partially offset by a lower average sales price

•Oil and gas royalty revenue increased $.7 million due to higher unit prices for        

natural gas sold, partially offset by a decrease in volume

•Revenues for hauling stumpage to other mills increased 24 percent, offset by hauling

expenses which are included in cost of sales

32

Cost of sales for the Woodlands segment for the first nine months of 2017 increased $1.3 million compared to the same period a year ago, primarily due to the following:

•Severance tax and other deductions on oil and gas royalty revenue increased $.3 million

period over period

•Hauling cost of stumpage to other mills increased 23 percent due to increased harvest

volumes compared the prior year and is offset by hauling revenue which is included in net

sales

The Woodlands segment's operating income was $1.8 million higher than in the first nine months of 2016, due to the same factors affecting net sales and cost of sales along with a $.4 million increase in general and administrative expenses allocated to the Woodlands segment.

¹Residual by-products are reported net of intercompany eliminations of $5 million in 2017 and $4.6 million in 2016.

Net sales for the Manufacturing segment increased $3.2 million from the prior-year period, primarily due to the following:

•Lumber sales volume increased four percent and the average sales price increased $11 per

MBF, or three percent

•MDF revenues decreased five percent due to lower sales volumes when compared to the

prior year period

34

Cost of Sales for the Manufacturing segment in the first nine months of 2017 increased $6.6 million from the first nine months of 2016. For the reported cost of sales for sawmill and MDF operation, intersegment elimination of residual sales by sawmill operation to MDF operation are not reflected.

•Raw materials cost increased six percent at the sawmills due to increased lumber

production

• Direct operating costs increased $4.8 million at the sawmills due to increased operating days and higher production

• Raw materials costs for the MDF plant decreased four percent as a result of lower production volumes due to planned capital and unplanned maintenance downtime in the second and third quarters of 2017

Manufacturing segment operating income was $4.3 million less than in the same period a year ago, due to the same items affecting net sales, and cost of sales, combined with an increase of $2.5 million in depreciation expense for the sawmill operations as major capital projects completed in the prior year begin to depreciate, and an increase in general and administrative expenses allocated to the Manufacturing segment.

Net sales for the Real Estate segment in the first nine months of 2017 increased $1.7 million when compared to the first nine months of 2016, due to the following:

• Residential lots sold increased to 77 from 53 a year ago

• Average sales price of $63,000 per lot sold in 2017 versus $80,000 per lot sold in 2016

• Sold 8 commercial acres for $392,000 per acre in 2017 compared to 11 acres for $152,000 per

acre in sold 2016

Cost of sales for the Real Estate segment increased $.2 million compared to the first nine months of 2016, due to the following:

• Increased number of residential lots and commercial acres sold in 2017 versus 2016

• Increase in commercial property sold in 2017 compared to 2016

The increase in operating income for the Real Estate segment from the first nine months of 2016 was due to the same factors affecting net sales and cost of sales, partially offset by an increase in general and administrative expenses allocated to the real estate segment.

Corporate

The Corporate operating expense in the first nine months of 2017 was $1.9 million lower than in the first nine months of 2016 due to decreased general and administrative expense; primarily salaries, benefits, and incentive expense.

Eliminations

Intersegment sales of timber from Deltic’s Woodlands to the Manufacturing segment increased $1 million to $15.9 million for the first nine months of 2017. Logs supplied by the Woodlands segment to Company sawmills are transferred at prices that approximate market.

Interest Expense

Interest expense for the first nine months of 2017 decreased $1.3 million due to a lower weighted-average interest rate when compared to the same period of 2016, and to an increase of $.4 million in patronage refunds received in 2017 compared to 2016, which is counted as a reduction in interest expense.

Income Taxes

The effective income tax rate was 43 percent for the first nine months of 2017, versus 33 percent for the first nine months of 2016. The increase in the current-year income tax rate is primarily due to the expiration of the favorable capital gains rates on timber harvested in 2016 and changes in reporting the discrete tax effects of equity-based compensation that increased the effective income tax rate five percent as the Company adopted Accounting Standards Update 2016-09 in the first quarter of 2017. (For additional information regarding income taxes, refer to Note 8 to the consolidated financial statements.)

Liquidity and Capital Resources

Cash Flows and Capital Expenditures

Net cash provided by operating activities totaled $23.3 million for the first nine months of 2017, compared to $28 million for the same period of 2016. Cash from operations provided the cash needed for capital expenditures and payment of dividends. Changes in operating working capital, other than cash and cash equivalents, required cash of $6.4 million in the first nine months of 2017 and provided $1.0 million in the same period of 2016, (For additional information refer to Note 15 to the consolidated financial statements.) The Company’s accompanying Consolidated Statements of Cash Flows identifies other differences between net income and cash provided by operating activities for each reporting period.

Capital expenditures required cash of $21.7 million in the current-year period and $32.4

million a year ago. Capital expenditures by segment consisted of the following:

	Nine Months Ended September 30,
(Millions of dollars)	2017			2016
Woodlands	$	2.6		2.8
Manufacturing	15.1			26.5
Real Estate, including development expenditures	4.2			4.2
Corporate	.2			.1
Capital expenditures	22.1			33.6
Adjustment for accrued liabilities	(.7		)	(1.2	)
Capital expenditures requiring cash	$	21.4		32.4

There were $.4 million timberland acquisition expenditures, for the nine months ended September 30, 2017 and $1.2 million in expenditures for the nine months ended September 30, 2016. The net change in purchased stumpage inventory to be utilized in the Company’s sawmill operations provided cash of $.6 million and required cash of $1.3 million in the first nine months of 2017 and 2016, respectively. There were no funds held by trustees to be used for acquisitions of timberland designated as "replacement property" for income tax purposes at September 30, 2017 or 2016. The Company borrowed $6 million and million repaid $8 million in the first nine months 2017, resulting in a $2 million reduction in net borrowings for the year. The Company borrowed $26 million and repaid $8 million in the first nine months of 2016. Dividends of $3.7 million were paid in the first nine months of both 2017 and 2016. The Company had no share repurchases in the first nine months of 2017 and used $15.2 million to repurchase shares in the first nine months of 2016. Other financing activities required cash of $.6 million in the first nine months of 2017 and $1 million for the same period of the prior year.

Financial Condition

Working capital totaled $14.7 million at September 30, 2017, and $10.2 million at December 31, 2016. Deltic’s working capital ratio at September 30, 2017 was 1.72 to 1, compared to 1.51 to 1 at the end of 2016. Cash and cash equivalents at the end of the third quarter of 2017 were $5.9 million, an increase of $.1 million from the December 31, 2016 balance of $5.8 million. The total indebtedness of the Company at September 30, 2017 was $239 million compared to $241 million at December 31, 2016. Deltic’s total debtto stockholders’ equity ratio was .935 to 1 at September 30, 2017 and .959 to 1 at December 31, 2016.

38

Liquidity

The primary sources of the Company’s liquidity are internally generated funds, access to outside financing, and working capital. The Company’s current strategy for growth continues to emphasize its timberland acquisition program, increasing harvest volume, expanding lumber production as market conditions allow and developing residential and/or commercial properties at Chenal Valley, Wildwood Place, and Red Oak Ridge.

To facilitate these growth plans, the Company has an agreement with a group of banks, which provides an unsecured and committed revolving credit facility totaling $430 million, and includes an option to request an increase in the amount of aggregate revolving commitments by $50 million. On July 29, 2016 the Company utilized a portion of the $50 million letter of credit component available under its revolving credit facility to replace the letter of credit that supports the Union County, Arkansas Taxable Industrial Revenue Bonds that total $29 million. As of September 30, 2017, there was $140 million outstanding in combined borrowings and letters of credit against the credit facility, leaving $290 million available. The credit agreement contains restrictive covenants, including limitations on the incurrence of debt and requirements to maintain certain financial ratios. (For additional information about the Company’s current financing arrangements, refer to Notes 8 and 9 to the consolidated financial statements included in the Company’s 2016 annual report on Form 10-K.)

The table below sets forth the covenants in the credit facility and senior notes payable and status with respect to these covenants as of September 30, 2017 and December 31, 2016.

	Covenants Requirements	Actual Ratios  at Sept. 30, 2017	Actual Ratios at Dec. 31, 2016
Leverage ratio should be less than:1	.65 to 1	.489 to 1	.490 to 1
Total outstanding debt as a percentage of total debt allowed based on the minimum timber market value covenant:2	— 2	77.25%	79.59%

^1.  The leverage ratio is calculated as total debt divided by total capital. Total debt includes indebtedness for borrowed money, secured liabilities, obligations in respect of letters of credit, and guarantees. Total capital is the sum of total debt and net worth. Net worth is calculated as total assets minus total liabilities, as reflected on the balance sheet. This covenant is applied at the end of each quarter.

^2.  Timber market value must be greater than 175 percent of total debt (as defined in (1) above.) The timber market value is calculated by multiplying the average price received for sales of timber for the preceding four quarters by the current quarter’s ending inventory of timber. This covenant is applied at the end of the quarter on a rolling four-quarter basis.

Based on management’s current operating projections, the Company believes it will remain in compliance with the debt covenants and have sufficient liquidity to finance operations and pay all obligations. However, depending on market conditions and the possibility of the return of economic deterioration, the Company could request amendments, or waivers for the covenants, or obtain refinancing in future periods. There can be no assurance that the Company will be able to obtain amendments or waivers, or negotiate agreeable refinancing terms should it become needed.

In December 2000, the Company’s Board of Directors authorized a stock repurchase program of up to $10 million of Deltic common stock. The Company’s Board of Directors expanded the program by $25 million in December 2007, by $25 million in December 2014, and by $20 million in February 2016. As of September 30, 2017, the Company had expended $56.9 million under this program, with the purchase of 1,099,054 shares at an average cost of $51.78 per share, with no share purchases occurring during the first

nine months of 2017. In its two previous repurchase programs, Deltic purchased 479,601 shares at an average cost of $20.89 per share and 419,542 shares at a $24.68 per share average cost, respectively.

Off-Balance Sheet Arrangements, Contractual Obligations, and Commitments

The Company has both funded and unfunded noncontributory defined benefit retirement plans that cover the majority of its employees. The plans provide defined benefits based on years of service and final average salary. Deltic also has other postretirement benefit plans covering substantially all of its employees. The health care plan is contributory with participants’ contributions adjusted as needed; the life insurance plan is noncontributory. With regard to all of the Company’s employee and retiree benefit plans, Deltic is unaware of any trends, demands, commitments, events or uncertainties that will result in or that are reasonably likely to result in the Company’s liquidity increasing or decreasing in any material way. (For information about material assumptions underlying the accounting for these plans and other components of the plans, refer to Note 15 of the consolidated financial statements included in the Company’s 2016 annual report on Form 10-K.)

Tabular summaries of the Company’s contractual cash payment obligations and other commercial commitment expirations, by period, are presented in the following tables.

Outlook

Deltic’s management believes that cash provided from its operations and the remaining amount available under its credit facility will be sufficient to meet its expected cash needs and planned expenditures, including those of the Company’s continued timberland acquisition, real estate development, and share repurchase programs, and capital expenditures, for the foreseeable future.

Critical Accounting Policies and Estimates

Critical accounting estimates are defined as those that are reflective of significant judgments and uncertainties and potentially result in materially different results under different assumptions and conditions. The Company has prepared its consolidated financial statements in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the reported amounts in these financial statements and accompanying notes. Actual results could differ

40

from those estimates under different assumptions or conditions. The Company has disclosed its critical accounting policies and estimates in its 2016 annual report on Form 10-K, and this disclosure should be read in conjunction with this Form 10-Q.

Impact of Recently Effective Accounting Pronouncements

(For information regarding the impact of recently effective accounting pronouncements, refer to Note 1 to the consolidated financial statements.)

Outlook

Pine sawtimber harvest levels are expected to be 275,000 to 300,000 tons in the fourth quarter of 2017 and 885,000 to 910,000 tons for the year. Finished lumber sales volumes are estimated at 75 to 85 million board feet for the fourth quarter and 295 to 305 million board feet for the year. MDF sales volumes for the fourth quarter and year of 2017 are estimated to be 20 to 30 million square feet and 95 to 105 million square feet, respectively. Actual lumber and MDF sales volumes are subject to market conditions. Residential lot sales are projected to be 70 to 80 lots and 150 to 160 lots for the fourth quarter and the year, respectively. The commercial real estate acreage within Chenal Valley continues to receive interest from potential buyers and in October 2017 Deltic sold the Company-owned, 35,000-square-foot retail center which is located at the key intersection of Rahling Road and Chenal Parkway for approximately $4 million. Due to the unpredictable nature of commercial real estate sales activity, the Company cannot predict the timing of closing of any other commercial real estate transaction.

Certain statements contained in this report that are not historical in nature constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “expects,” “anticipates,” “intends,” “plans,” “estimates,” or variations of such words and similar expressions are intended to identify such forward-looking statements. These statements reflect the Company’s current expectations and involve certain risks and uncertainties, including those disclosed elsewhere in this report. Therefore, actual results could differ materially from those included in such forward-looking statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company’s market risk has not changed significantly from that set forth under the caption “Quantitative and Qualitative Disclosures About Market Risk,” in Item 7A of Part II of its 2016 annual report on Form 10-K. Those disclosures should be read in conjunction with this Form 10-Q.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Deltic Timber Corporation (the “Company” or “Deltic”) has established disclosure controls and procedures to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the officers who certify the Company’s financial reports and to other members of senior management and the Board of Directors.

We carried out an evaluation, under the supervision and with the participation of our Chief Executive Officer and interim Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered in this report. Based upon that evaluation, our Chief Executive Officer and interim Chief Financial Officer concluded that due to a material weakness in our internal control over financial reporting as described in Item 9A-Controls and Procedures in our 2016 Annual Report on Form 10-K, our disclosure controls and procedures were not effective as of September 30, 2017.

Due to the material weakness in internal control over financial reporting, we dedicated resources to perform additional procedures prior to filing this Periodic Report on Form 10-Q. These additional procedures have allowed us to conclude that, notwithstanding the material weakness in our internal control over financial reporting, the consolidated financial statements included in this report fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States of America.

Changes in Internal Control Over Financial Reporting

Other than the steps taken to work towards the remediation of the material weakness discussed below, Deltic’s management, with the Chief Executive Officer and interim Chief Financial Officer, have evaluated all changes in the Company’s internal control over financial reporting that occurred during the Company’s most recent fiscal quarter, and have concluded that there was no change to Deltic’s internal control over financial reporting that has materially affected or is reasonably likely to materially affect Deltic’s internal control over financial reporting.

Remediation Plan

We are committed to remediating the material weakness caused by ineffective controls over the cash disbursements process for certain expenditures that require payment on an expedited basis. During the first quarter of 2017, as the result of the misappropriation of assets and related control deficiencies described in Item 9A-Controls and Procedures in our 2016 Annual Report on Form 10-K, the Company initiated comprehensive remediation efforts to ensure that the deficiencies that contributed to the material weakness are remediated. We have reviewed the design, implementation and operation of the controls and have made enhancements and identified new controls that were implemented as part of the remediation efforts. These efforts include establishing a segregation of duties between the initiation and authorization of cash disbursements for expenditures and enhancing documentation requirements around check authorizations.

We believe that such efforts, once fully implemented and operating for a sufficient period of time, will effectively remediate the reported material weakness. However, the material weakness will not be considered remediated until the controls operate for a sufficient period of time and management has concluded, through testing, that these controls are designed and operating effectively.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, the Company is involved in litigation incidental to its business. Currently, there are no material legal proceedings.

Item 1A.Risk Factors

There have been no material changes from the risk factors previously disclosed in Item 1A of Part I in the Company’s 2016 annual report on Form 10-K.

Pending Merger with Potlatch Corporation

On October 22, 2017, Deltic and Potlatch entered into a Merger Agreement pursuant to which Deltic will merge with and into a wholly-owned subsidiary of Potlatch ("Merger Sub") with Merger Sub continuing as the surviving corporation. If the merger is not completed, our businesses may be adversely affected and we may be subject to various risks without realizing any of the benefits of having the merger completed, including the following:

• We may be required, under certain circumstances, to pay a termination fee of $33 million.

• We may be required to reimburse Potlatch for all reasonable documented out-of-pocket fees, and expenses incurred in connection with the Merger Agreement and the merger.

• We may experience negative reactions from the financial markets or from our customers, suppliers or employees.

• We may be subject to litigation related to failure to complete the merger or to enforcement proceedings to perform our obligations under the Merger Agreement.

A delay in completing the merger, which is subject to a number of conditions, some of which are outside our control, may reduce or eliminate the expected benefits from the merger.

The merger is subject to a number of conditions, some of which are beyond our control, that could prevent, delay or otherwise materially adversely affect its completion. We cannot predict whether and when the conditions will be satisfied. The requirement to obtain certain regulatory approvals could delay the completion of the merger for a significant period of time or prevent it from occurring. A delay in completing the merger could cause the combined company not to realize some or all of the synergies and other benefits that it expects to achieve if the merger is successfully completed within its expected time frame. The Merger Agreement contains certain restrictions on the conduct of our business. If the merger is delayed these restrictions could adversely affect our ability to execute business strategies or pursue attractive business opportunities. In addition, a delay could cause management to focus on completion of the merger instead of on other opportunities that could be beneficial to the company.

The merger will involve substantial costs, and the combined company may be unable to successfully integrate the businesses of the two companies and realize the anticipated benefits of the merger.

We have incurred and expect to continue to incur substantial costs and expenses relating directly to the merger, including fees and expenses payable to financial and other professional advisers, SEC filing fees, printing and mailing costs and other transaction-related costs, fees and expenses. We expect to incur substantial expenses in connection with the integration of the businesses, policies, procedures, operations, employees, technologies and systems of Deltic with those of Potlatch. There are a large number of systems that must be integrated, including management information, purchasing, accounting and finance, sales, billing, payroll and benefits, fixed asset and lease administration, and regulatory systems.

Accounting Policies

Basis of Presentation

The consolidated financial statements have been prepared by Deltic Timber Corporation (the “Company” or “Deltic”). Certain information and accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations of the Securities and Exchange Commission. Although management of the Company believes the disclosures contained herein are adequate to make the information presented not misleading, these consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2016. Preparation of consolidated financial statements requires management to make estimates and assumptions. These estimates and assumptions affect reported amounts of assets and liabilities, disclosure of contingent assets, and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Management believes the accompanying consolidated financial statements contain all adjustments, consisting of only normal recurring accruals and adjustments, which in the opinion of management are necessary to present fairly its financial position as of September 30, 2017, and the results of its operations and cash flows for the three months and nine months ended September 30, 2017 and 2016. These consolidated financial statements are not necessarily indicative of results to be expected for the full year. The Company has evaluated subsequent events through the date the financial statements were issued.

Recently Issued Authoritative Accounting Pronouncements and Guidance

Effective January 1, 2017, the Company adopted Accounting Standard's Update ("ASU") 2016-09, “Improvements to Employee Share-Based Payment Accounting”. This standards update simplified several aspects of the accounting for share-based payments award transactions, including accounting for income taxes, classification of excess tax benefits on the statement of cash flows, forfeitures, minimum statutory tax withholding requirements, and the classification on the statement of cash flows of employee taxes paid when an employer withholds shares for tax-withholding purposes. As a result of the adoption, Deltic recognized approximately $500,000 of tax shortfalls from share-based compensation as a discrete item of income tax expense during the first quarter of 2017. Historically, these amounts were recorded as activity in additional paid-in capital. Deltic elected to apply the standards update pertaining to cash flows prospectively, therefore prior-year statements have not been adjusted. Deltic elected to account for forfeitures as they occur rather than using a requisite estimated forfeiture rate for future forfeitures. The additional changes related to the standard's update and the election to change accounting methods for forfeitures did not have a material impact on the Company's financial statements.

Effective January 1, 2017, the Company adopted ASU 2015-17, "Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes". This standards update requires that all deferred tax assets and liabilities be offset and presented as a single, non-current, amount. Historically, deferred tax items were presented on the Balance Sheet as current and non-current. The Company applied this standard's update prospectively, combining current deferred tax assets of $1,895,000 with non-current deferred tax liabilities, for a net long-term tax asset balance of $151,000 at January 1, 2017.

In March of 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-07, "Improvements to the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which requires the service cost components be reported separately from other components of net

periodic pension costs and be reported on the same line item as other compensation costs. This update is effective for the Company on January 1, 2018 and is not expected to have a material impact on its financial statements.

In May of 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue it expects to be entitled to for the transfer of promised goods or services to customers. This ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. The Company continues to evaluate the standard and has not yet selected a transition method but believes the standard is expected to have little impact on its consolidated financial statements other than updated disclosures.

In February 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-02, “Leases”, which supersedes Topic 840 and among other things, requires lessees to recognize most leases on-balance sheet. The new standard will be effective for the Company on January 1, 2019, and is not expected to have a material impact on its financial statements.

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments”. The ASU changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life. This update will be effective for the Company on January 1, 2020, and is not expected to have a material impact on its financial statements.

Deltic acquired 341 acres of timberland for $353,000 during the three and nine months ended September 30, 2017. During the three months ended September 30, 2016, Deltic acquired 220 acres of timberland for $514,000, and for the nine months ended September 30, 2016, Deltic acquired 623 acres of timberland for $1,207,000. Deltic invests in and holds strategic fee timber as a productive asset, and any expenditure to acquire such timber and timberlands is an investing activity on the Company’s Consolidated Statements of Cash Flows.

The Company actively upgrades its timberland portfolio by selling non-strategic timberlands and using the sales proceeds to purchase pine timberlands that are strategic to its operations. The Company identifies tracts of pine timberland that cannot be strategically managed due to size or location, and also tracts of hardwood bottomland that cannot be converted into pine-growing acreage, to be sold. As of September 30, 2017, approximately 1,500 acres of these lands were available for sale.

Income Taxes

Income Taxes

The Company’s effective income tax rate for the three months and nine months ended September 30, 2017, was 39 and 43 percent, respectively. This compares to an effective income tax rate for the three and nine months ended September 30, 2016, of 38 and 33 percent, respectively. The prior-year effective rate was reduced by the lower capital gains tax rates applied on the sale of timber held 15 years or longer which expired December 31, 2016. Conversely, the effective income tax rate exceeded statutory income tax rates during the first nine months of 2017 due to discrete items related to the changes in the method of recognizing income tax benefits and shortfalls on the vesting of share-based compensation by the adoption of ASU 2016-09 in the first quarter. At September 30, 2017, there were no unrecognized tax benefits recorded on the balance sheet. The Company is no longer subject to U.S. federal and state examination by tax authorities for years before 2013.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Fair Value Measurement Accounting establishes a fair value hierarchy based on the quality of inputs used to measure fair value, with Level 1 being the highest quality and Level 3 being the lowest quality. Level 1 inputs are quoted prices in active markets on identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included in Level 1. Level 3 inputs are unobservable inputs which reflect assumptions about pricing by market participants.

The following is a description of the valuation methodologies used for assets and liabilities measured at fair value.

Nonqualified employee savings plan – Consists of mutual funds, which are valued at the net asset value of shares held by the plan at the balance sheet date, at quoted market prices.

The fair value measurements for the Company’s financial liabilities accounted for at fair value on a recurring basis at September 30, 2017, are presented in the following table

	Fair Value Measurements at Reporting Date using

Subsequent Event

Subsequent Event

On October 23, 2017, Deltic Timber Corporation and Potlatch Corporation announced that they had entered into a material definitive agreement to combine in an all-stock transaction ("the transaction"). The combined company will be named PotlatchDeltic Corporation and its shares will trade on the Nasdaq Stock Market under the ticker PCH.

Under the terms of the agreement, which have been unanimously approved the Boards of Directors of both companies, Deltic stockholders will receive 1.80 common shares of Potlatch stock for each common share of Deltic that they own. The transaction is subject to shareholder approval by both Potlatch and Deltic shareholders, as well as regulatory approval. Following the close of the transaction, Potlatch stockholders will own approximately 65% of the combined company, and Deltic stockholders will own approximately 35% on a fully diluted basis.

In connection with the announced transaction, the Company has incurred an $11 million liability related to transaction advisory fees, which management expects to be expensed in the fourth quarter of 2017. Additionally, transaction advisory fees of $4 million may be incurred in the first half of 2018. The payment of such expense is currently expected to be made in the first half of 2018. The Company also anticipates incurring additional transaction related expenses in the fourth quarter of 2017 and first half of 2018, which may be material to the Company's financial statements.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The consolidated financial statements have been prepared by Deltic Timber Corporation (the “Company” or “Deltic”). Certain information and accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations of the Securities and Exchange Commission. Although management of the Company believes the disclosures contained herein are adequate to make the information presented not misleading, these consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2016. Preparation of consolidated financial statements requires management to make estimates and assumptions. These estimates and assumptions affect reported amounts of assets and liabilities, disclosure of contingent assets, and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Management believes the accompanying consolidated financial statements contain all adjustments, consisting of only normal recurring accruals and adjustments, which in the opinion of management are necessary to present fairly its financial position as of September 30, 2017, and the results of its operations and cash flows for the three months and nine months ended September 30, 2017 and 2016. These consolidated financial statements are not necessarily indicative of results to be expected for the full year. The Company has evaluated subsequent events through the date the financial statements were issued.

Recently Issued Authoritative Accounting Pronouncements and Guidance

Recently Issued Authoritative Accounting Pronouncements and Guidance

Effective January 1, 2017, the Company adopted Accounting Standard's Update ("ASU") 2016-09, “Improvements to Employee Share-Based Payment Accounting”. This standards update simplified several aspects of the accounting for share-based payments award transactions, including accounting for income taxes, classification of excess tax benefits on the statement of cash flows, forfeitures, minimum statutory tax withholding requirements, and the classification on the statement of cash flows of employee taxes paid when an employer withholds shares for tax-withholding purposes. As a result of the adoption, Deltic recognized approximately $500,000 of tax shortfalls from share-based compensation as a discrete item of income tax expense during the first quarter of 2017. Historically, these amounts were recorded as activity in additional paid-in capital. Deltic elected to apply the standards update pertaining to cash flows prospectively, therefore prior-year statements have not been adjusted. Deltic elected to account for forfeitures as they occur rather than using a requisite estimated forfeiture rate for future forfeitures. The additional changes related to the standard's update and the election to change accounting methods for forfeitures did not have a material impact on the Company's financial statements.

Effective January 1, 2017, the Company adopted ASU 2015-17, "Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes". This standards update requires that all deferred tax assets and liabilities be offset and presented as a single, non-current, amount. Historically, deferred tax items were presented on the Balance Sheet as current and non-current. The Company applied this standard's update prospectively, combining current deferred tax assets of $1,895,000 with non-current deferred tax liabilities, for a net long-term tax asset balance of $151,000 at January 1, 2017.

In March of 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-07, "Improvements to the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which requires the service cost components be reported separately from other components of net

periodic pension costs and be reported on the same line item as other compensation costs. This update is effective for the Company on January 1, 2018 and is not expected to have a material impact on its financial statements.

In May of 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue it expects to be entitled to for the transfer of promised goods or services to customers. This ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. The Company continues to evaluate the standard and has not yet selected a transition method but believes the standard is expected to have little impact on its consolidated financial statements other than updated disclosures.

In February 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-02, “Leases”, which supersedes Topic 840 and among other things, requires lessees to recognize most leases on-balance sheet. The new standard will be effective for the Company on January 1, 2019, and is not expected to have a material impact on its financial statements.

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments”. The ASU changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life. This update will be effective for the Company on January 1, 2020, and is not expected to have a material impact on its financial statements.
